HENRY TRABBOLD, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE J. G. BRILL COMPANY, OF PHILADELPHIA, PENNSYLVANIA A CORPORATION OF PENNSYL? VANIA.

DOUBLE CONTROL MECHANISM FOR DOORS.

Specification of Letters Patent.

Patented July 25, 1916.

To all whom it may concern:

Be it known, that l, HENRY TRABBOLD, a citizen of the United States, and a resident of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain Improvements in Double Control Mechanism for Doors, of which the following 1s a specification.

My invention relates to certain improvements in the means for operating doors and, in some instances, the steps of passenger cars of the type used in city and suburban travel, the motormans station being located at the front of the car and the conductors station being placed at or near the rear platform.

One object of the invention is to construct the operating mechanism for the doors at the ends of the car so that the same mechanism can be used either by the motorman or by the conductor.

A further object of the invention is to provide means whereby either of the operating means may be disconnected when the other is used.

In the accompanying drawings: Figure 1 is a longitudinal sectional elevation through the center of a car platform, looking toward the doors at the side of the car and illustrating the mechanism for operating the doors; Fig. 2 is aseetional elevation on the line a-a, Fig. 1; Fig. 3 is a sectional plan view on the line bb, Fig. 1; Fig. at is a detached perspective view illustrating the operating mechanism; Fig. 5 is an enlarged View showing the clutching mechanism for the motormans operating shaft; Fig. 6 is a sectional view on the line cc, Fig. 5; Fig. 7 is a sectional view on the line clal, Fig. 5; Fig. 8 is a detached perspective view of one end of the motormans shaft; Fig. 9 is a sectional view on the line e-c, Fig. 7; Fig. 10 is a side view of the conductors operating handle; Fig. 11 is an enlarged side view of a portion of the vertical operating rod; Fig. 12 is a sectional view on the line f-f, Fig. 10; Fig. 13 is a sectional view on the line gg, Fig. 11; and Fig. 14 is a view of a modification.

Referring to the drawings, 1 is the body of the ear.

2 is the floor of the platform.

3 is the front bulkhead of the platform in which are located the usual mechanisms for operating the car. In the present instance, the motormans station is at the point a at the forward end of the platform and the conductors station is at the point g on the platform, but, in some cases, the conductors station may be inside of the car, the mechanism being extended accordingly.

4 is the roof, which extends over the platform in the usual manner.

5 and 6 are the doors located at one side of the platform. Each of these doors is a double door and is separated, in the present lnstance, by a central post 7, although this post may be omitted in some cases. The door 5 is pivoted at 8 and the door 6 is pivoted at 9.

Mounted in hangers 11 secured, in the present instance, to the roof of the car platform is an operating shaft 10. On the shaft is a slotted arm 12 connected to an arm 13 on a sleeve 14 mounted on a rod 15 secured to the plates on the hangers 11. The arm 13 has pins which enter the slots in the arm 12, which is bifurcated in the present instance. On the sleeve 14: is a second arm 16 connected by a rod 17 to an arm 18 on the pivot rod 8 to which the door 5 is attached so that when the shaft 10 is turned the motion will be imparted to the rod 8 to open or close the door. On the rod 8 is an arm 19 connected by a rod 20 to an arm 21 on the rod 9 of the door 6. One of these arms projects inward and the other projects outward, as clearly shown'in Fig. 3, so that the doors may open or close in unison when the shaft is turned. On the shaft 10 is an arm 22 connected by a vertical rod 23 to an arm 24 under the platform 2 of the car. This arm projects from a sleeve 25 which is mounted on a spindle 26 carried by hangers 27 secured to the under side of the platform, as shown in Fig.

2. On the sleeve 25 is an arm 28 connected by a rod 29 to a lug 30 on the step 31, which is pivoted at 32 to the framework 2 of the platform 2 and the mechanism is so mounted that when the rod 23 is moved in one direction the doors will be opened and the step will be lowered,but when it is moved in the opposite direction the doors will be closed and the step will be raised. The rod 23 is flattened at 23 and is preferably tapered, as shown in Fig. 13, to receive the detachable hand hold 33. The hand hold is forked, as shown in Fig. 12, and has a spring clip 34, which enters a recess 35 in the flattened portion'23 of the rod and locks the hand hold to the rod to enable the operator of the motorman.

to move the rod longitudinally to open and close the-doors. When the conductor moves from one end of the car to the other he detaches this hand hold and places it on the rod at the opposite end of the car.

In order to allow the motorman to operate the door at the front of the car, I provide a shaft 36 which is mounted in a bearing l1 at one end and the opposite end of this shaft rests in a recess 10 in the shaft, as clearly shown in Fig. 5. The end of the shaft within the sleeve is beveled, as at 37, to form a member of a clutch while the base of the recess 10 is beveled at 38 to correspond with the bevel at the end of the shaft and forms the other member of the clutch,

so that when the rod 36 is moved longitudinally by the motorman to permit the two beveled surfaces to engage one another then the shaft 10 is turned with the shaft 36 and when the shaft 36 is withdrawn by a longitudinal movement the two shafts are independent. On the outer end of the shaft 36 is a rope wheel 39 to which is attached a rope 4:0 having hand holds 41 within reach A spring catch 42 on the shaft 36 near the clutch end enters an annular recess 43 in the shaft 10, Fig. 5, when the shaft 36 is moved into engagement with the shaft 10 and acts to retain the shaft 36 in position. When the shaft is withdrawn, as in Fig. 5, a catch 44: enters a recess 45 in the bearing 11 to hold the clutch out of action, as in Fig. 9.

The above described mechanism is located, in the present instance, on the platform at each end of the car and at the forward end the motormans shaft 36 is clutched to the shaft 10 and the conductors hand hold 33 is removed from the rod 23. At the rear end of the car the hand hold 33 is in position and the motormans shaft 36 is withdrawn from engagement with the shaft 10 so that the doors cannot be operated from this point. In some instances, the mechanism is so arranged that the rod 23 is operated by the motorman and the rope wheel operating mechanism. ()n the outer end of the shaft 10 is the operating wheel 39 and this wheel can be clutched to the shaft by a bolt 46 so that when the bolt is withdrawn the shaft cannot be actuated from the motormans station and when the hand hold is detached the rod 23 cannot be readily moved 7 having a door at one side; an overhead opcrating mechanism including a longitudinal shaft having two operating devices, one at the motormans station and one at the conductors station; and clutch mechanism by which the operating device at the motormans station may be connected to or disconnected from the said longitudinal shaft.

2. The combination in a passenger car, of a door; an overhead shaft connected to the door; a vertical rod connected to the overhead shaft; means for raising and lowering said rod to open and close the door; a wheel at the motormans station; means for turning the wheel in either direction; and clutch mechanism between the wheel and the overhead shaft so that the wheel can be disconnected from the shaft when necessary.

3. The combination in a passenger car, of a platform; a door at the side of the platform; ashaft; means connecting the shaft with the said door; a second shaft arranged to be coupled to the first mentioned shaft; a
